96 CPI into 92 S-10 TBI

Got a 92 Blazer (4.3 TBI stick) needing a motor. Want to install a 96 Goodwrench 4.3 with balancer shaft, CPI, and the better heads. Is this done all the time? I will buy a new engine wiring harness....is the fuel pump OK?
Any other issues?

You'll need a new computer, one from a 96' 4.3 CPI with stick; a computer from a vehicle with auto trans won't work. That, along with the wire harness, and welding 02 bungs on the post cat pipe. Oh, and the EVAP emissions have a few extra wires here and there. Hell, just use the long block from the newer motor and buy a TBI intake that will fit the Vortec heads. It'll be cheaper by several hundred bucks as wiring harnesses are big $$ and all the extra wiring you'll have to run will take forever.

I agree with the Doc:
Also, while you put on the newer manifold. Put in a throttle body spacer for a marked performance improvement.
The rewiring, if you are in the technical league to do it. (No disrespect intended) would take many, many hours. Then the diagnostics to see why something doesn't work would have you babbling and beating your head against the wall.
